A thing that also really helped me I found in a footnote of Functional Javascript. There the idea of a "free variable" is presented not as free as in freedom, or even free as in beer. But free as in escaped. The variable hitches a ride in the closure and is no longer jailed in its defining scope, and lives on much longer than it normally would. I found that to be a really valuable shift in the way I processed the phrase "free variable". |
